To all win/mi). may concern:

Be it. lflnmll that l, Tnoniis l-l. WALKER, d citizen of the lfnited States, residing at Kansas City, in the county of Jackson and Male of Missouri. have invented certain new and usel'ul lm nrovements in Sheet-Metal- Rznlintor Mnnul'acture, of which the following is a specification.

My invention relates to improvements in sheet metal radiator manufacture.

it relat s mvicularly to she ct metal radi al'ors composed ot a plurality of connected sheet metal sections each section comprising two sheet metal halve," a

The object. of my invention is to provide. a sheet metal radiator section of the. typo described in which the outeredges of the halves are tightly joined, and each half is provided with an imperl'orate panel portion interlocked with a similar panel portion ofthe opposite half, whereby the radiator section is greatly strengthened and leakage inwardly or outwardly through. the pnneled port-ion, due to intqmal or external pressure, is wholly avoided Another object of my invention is to pro-v vide an improved method or process of mak- 11] my nnproved sheet metal radiator section.

y invention. provides further, novelmcans by which the radiator sections are firmly held together and leakage at the places of connect-ion is avoided.

My invention provides further a construction of shoot metal radiator in which, rad iator sections may he roadily added to or removed from a radiator, thereby permitting the quick constructionof a radiator ofanydesired capacity.

Other novel features of my invention :I hereinafter fully described and claimed.

Similar characters 0'1 rgfiirencc denote si1ni'- V lar parts. I

I will iirst describe tlie construction of and mcthod of making my' improved radiator section. Each radiator section comprises two sheet metal halves or members" 1 and2, the outer edges of which arc tightly joined to each other, preferably by a, lapseam in which the peripheral 'llange 3 of the sheet 1 is over lapped by the peripheral llange l which extends around tho outer edge of the shoot 2. The sheets 1; and 2 are provided on their ad joining sidcs with depressed portions which register n ith each other and form a line space 5 into which the heating iluid, such as steam, is admitted. Each sheet is provided with a central longitudinal lHlDCl portion which interlocks with the oppositc panel portion,

thereby strengthening the. section. "In myimprovci'l construction. this panel portion. is "impcrforatc, and there is, therefore, no 013* portunity for the. heatinglluid to escape where the panel portions of opposite sheets join, nor, when a partial vacuum occurs due to steam condensation, our; air enter the radiator section. By my improved process the-sheet 1- has formed therein a central longitudinal boss 6 :ulapted to fit into a corresponding boss 7 when theshcots- 1 and 2 are placed side h side. with their outer edges ahuttingcacli other. The bosses 6 and. 7 are then interlocked, preferably by upsetting the side walls thereof, as shown b'y'8 in Fig. 4. The dcpres'sions in the sheets which form the line space5 cncircle the bosses 6 and 7. Prior to placing the shoots side by side, each sheet adjacent its upper and lower ends is pro-- vided with two porforations 9, each enclrclcd'b -i an inwardly extending tapering annular ilangc 10. The flanges 1.0 in adjacent ends oi. sheets 1. and Z are. oppositely disposed .hut (lo-not meet. The sheet-2 is slightly arger than the sheet 1 so that when. placed idc by side as described, the outer edge of the. sheet 2 may he lapped over the outer edge oi the. sheet 1, thus forming an inwardly ox:

tending flange, 4 which is tightly compressed against the. flange-3.1m the manner usual 1f forming a lap scam. s

30 are provided; Said thimbles are each tubular throughout and are each provided with Corresponding ends of the several radiator sections are connected with each other in the manner 1 will now describe. I

As the upper and low er ends of the radiator SGChlOIlSe-fil'fir connected to adjacent sections in the same manner, a description of the mechanism connecting the upper radiator ends, as illustrated in Fig. 3, will suflice also for a description of the mechanism connecting together the lower ends of the sections.

Ineach section is provided a horizontal sleeve 11, the inner wall of which tapers from the ends toward the middle Said ta ering walls encircle the tapering annular anges 10 in the adjacent end of the radiator section, The sleeve 11 is provided intermediate the ends of the flanges 10 with one or more e- :ripheral openings 12. Horizontal tubu ar thin bles 13 connect adjacent radiator sections, Each of these intermediate thimbles comprises a tube having its outerwall tapering from'the middle toward each end.

The tapering ends'of each intermediate thirnble 13 is inserted in the adjacent annular flanges "1-0 of adjacent sections.- The diameter of the intermediate thimble 13 is such that When foyced lengthwise into the flanges 10 it willtlghtly compress said flanges against the inner tapering Wallof the sleeve 11 which encircles such flanges. Two and thimhles 1.4

an outer wall having a tapering inner end.

' I Said thi'mbles 14 are respectively mounted in,

the outerfepnular flanges 10"of the end sec-, tions, and respectively compress ,the said flanges 10 against. the inner walls of the two' endsleeves 11/ Each endthimble 14 is provided at its inner end-with an internal ann'ular flange 15. 'iRotatively mounted in theend thimbles .14 aretwo nuts '16 each'havmg one ormo relongitudinal perforations 17.

' which serve as means forturn'ing-said nuts I 'andalso to permit the 7 actively repented on: the Screw; threaded" ds' of a horizontal rod 18" disposed lohgitw' dinally in thethihlblu f3 and 14. The nus sides of the annu ar thimbles 14.

16. are respectivel 'sufppoeted by the/outer The parts having been hssemhied scribed to tightl connect the flift'ercntradi 1 the rod '18, thereby "bles 14 toward ea jacent sleevesrlll her-outer ends of four end thimbles' 14in each-radiator are! ternall screw threaded. In on'eof the-upper end thimbles 1145s secured theend of one 1 5 of theend L" of the stealn pipes, denoted hy the opposite lower thimble 14 is fitted one end 0' the other steam pipe denoted by 20. Removable threaded lugs 21 are mounted respectively in the ot or two end thimbles 14. By removing the plugs 21, the nuts 16 adjacent thereto may be rendered accessible for the purpose of tightening or loosening the same.

To increase or decrease the number of radiator sections, it is but necessary to supply duplicate parts as needed, or remove sections not neec ed, together with the connecting intermediate thnnbles 13 not required, and employ rods 18 of suitablelength.

Having thus described my invention, what I claim and desire to secure by Letters Pat ent, is
